SE is giving 1.0 player another chance to change their name. Here is a rule that i would like to be clarified

-Please note that once you receive the Character Name Change Screen, you will no longer be able to choose the same name your character currently possesses; you will have to choose a different name. Please be aware of this when you submit your request.-

If you want to change only your surname, will you be able to keep the same first name as before the change, or both name need to change ?
